At equilibrium, a graph showing reactant and product concentration versus time will have which of these characteristics?

a) an increasing slope for both reactant and product
b) a decreasing slope for both reactant and product
c) a decreasing slope for reactant and an increasing slope for product
d) an increasing slope for reactant and a decreasing slope for product
e) a zero slope for both the reactant and the product

e) a zero slope for both the reactant and the product
are you sure?
I apologize for the confusion. I misunderstood your question. At equilibrium, the graph of reactant and product concentration versus time will have a zero slope for both the reactant and the product. This is because at equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction, resulting in a constant concentration of both reactants and products. Therefore, the correct answer is e) a zero slope for both the reactant and the product.
